The heating sleeve is arranged, so that a runner through which the injection molding liquid passes is changed from a cold runner into a hot runner, and the fluidity of the injection molding liquid is increased, thereby improving the production efficiency; the runner plate is omitted, the injection molding liquid is provided with a sprue main runner which directly enters the cavity through the feed inlet, and no stub bar is generated, so that full-automatic production can be realized in production, the production efficiency is improved, and the labor cost of workers is reduced.
Description
Technical Field
The utility model relates to an injection mold technical field, concretely relates to two board spot gate moulds.
Background
As shown in fig. 1, among the prior art, three-plate spot-casting injection mold includes a plate 1', runner plate 6 and cover half 2', a plate 1', runner plate 6 and cover half 2' set gradually from right to left, be provided with runner sprue 4 'on a plate 1', and in runner sprue 4 'stretched into runner plate 6, be provided with a plurality of feed inlets 5' on cover half 2 'to through runner sprue 7 and the intercommunication of runner sprue 4' that set up on runner plate 6, runner sprue 7 corresponds the position department of every feed inlet 5 'and all is provided with one and runs through a material taking port of plate 1' and runner plate 6, be provided with the floating bolt in the material taking port. The injection molding liquid enters from the sprue main runner 4', then flows to each feed inlet 5' through the sprue sub-runner and flows 7 to enter the cavity, and the pouring is finished.
The casting mode can generate stub bars on the sprue runner and runner, the die can only adopt semi-automation due to the stub bars, the production efficiency is low, the stub bars need to be cleaned every time, the labor intensity of workers is increased, and meanwhile, the service life of the die is short; and the channel that the injection molding liquid passes through is the cold runner, and the mobility is poor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses plan to provide a two board spot gate moulds, can adopt full-automatic production, production efficiency is high and do not have the production of stub bar.
Therefore, the utility model discloses the technical scheme who adopts does: the utility model provides a two board spot gate moulds, includes A board and cover half, A board and cover half from left to right set gradually, the middle part of A board is provided with the runner sprue, the runner sprue runs through A board and stretches into the middle part of cover half left, the cover half corresponds the position department of runner sprue is provided with the feed inlet, feed inlet and runner sprue intercommunication, the feed inlet stretches into in the die cavity, the runner sprue overcoat is equipped with the heating jacket, the heating jacket is used for heating the fluid in the runner sprue.
Preferably, the board a is provided with a heating socket, the heating socket and the heating jacket are electrically connected through a lead, and the heating socket is arranged to heat the heating jacket.
Preferably, the heating sleeve is provided with a temperature sensing element for sensing the temperature of the heating sleeve, and the temperature sensing element is electrically connected with the heating socket through a lead to prevent the temperature of the heating sleeve from being too high or too low, so that the generation of defective products is reduced.
Preferably, the cross section of the sprue main runner is gradually increased, and the cross section of the feed inlet is gradually decreased, so that the injection molding liquid can flow conveniently.
The utility model has the advantages that:
(1) the heating sleeve is arranged, so that a runner through which the injection molding liquid passes is changed from a cold runner into a hot runner, and the fluidity of the injection molding liquid is increased, thereby improving the production efficiency;
(2) the runner plate is cancelled, so that the injection molding liquid is directly fed into the cavity through the feed inlet by the sprue main runner without producing a stub bar, and the stub bar is not required to be cleaned independently in production, so that full-automatic production can be realized, the production efficiency is improved, the labor cost of workers is reduced, and the service life of the mold can be prolonged;
(3) the runner plate can be taken from the original three-plate mold, the sprue main runner on the original A plate is enlarged, the heating sleeve can be placed in the sprue main runner, the sprue main runner is changed on the basis of the original mold, the mold does not need to be manufactured again, and the cost is saved.
Drawings
Fig. 1 is a schematic structural diagram of the prior art.
Fig. 2 is a schematic structural diagram of the present invention (without heating socket and wire).
Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
combine shown in fig. 2, a two board spot runner mould mainly is by A board 1, cover half 2, heating jacket 3, runner sprue 4 and feed inlet 5, and A board 1 and cover half 2 from left to right set gradually, and the middle part of A board 1 is provided with runner sprue 4, and runner sprue 4 runs through A board 1 and stretches into the middle part of cover half 2 left, and the position department that cover half 2 corresponds runner sprue 4 is provided with feed inlet 5, advances feed inlet 5 and runner sprue 4 intercommunication, in feed inlet 5 stretches into die cavity 2a, 4 overcoat of runner sprue is equipped with heating jacket 3, and heating jacket 3 is used for heating the interior fluid of runner sprue 4.
Preferably, a heating socket is arranged on the A plate 1, the heating socket is electrically connected with the heating jacket 3 through a conducting wire, and the heating socket is arranged to heat the heating jacket.
Preferably, the heating jacket 3 is provided with a temperature sensing element for sensing the temperature of the heating jacket 3, and the temperature sensing element is electrically connected with the heating socket through a lead, so as to prevent the temperature of the heating jacket 3 from being too high or too low, so that the temperature of the heating jacket 3 is kept within a certain range, and the generation of defective products is reduced.
Preferably, the cross-sectional area of the sprue main runner 4 is gradually increased, and the cross-sectional area of the feed inlet 5 is gradually decreased, so that the injection molding liquid can conveniently circulate.
Before injecting the injection molding liquid, the two-plate point gate mold needs to electrify the heating socket first so that the heating sleeve 3 reaches a preset temperature range.
